This paper presents a robust passivity-based control (RPBC) strategy for half-wave zero-voltage switching quasi-resonant (HW-ZVS-QR) buck and boost type converters. The proposed controller is based on energy shaping damping injection. Theoretical analysis shows that the resulted closed-loop HW-ZVS-QRs are globally asymptotically stabilised even if physical constraint magnitude of signal taken i...

AbspuctThe saturable inductor is employed in the fullbridge (FB) zero-voltage-switched (ZVS) pulsewidth-modulated (PWM) converter to improve its performance. The current and voltage stresses of the switches as well as parasitic oscillations are significantly reduced compared to those of the conventional FBZVS-PWM converter. The qualitative analysis is presented and is verified on a 500 KHz, 5 V...

The main purpose of this paper is the development a DC/DC boost converter with high conversion efficiency. proposed has step-up ratio and equipped soft-switching technology. inductor used in developed coupled rather than general inductor, therefore, voltage can be improved, so that characteristics power switch obtained within same duty cycle. connected to resonance branch circuit traditional co...

This paper introduces a new DC–DC structure with high voltage gain. The proposed can achieve higher gain by using magnetic coupling and multiplier circuit (VMC). VMC is also used as clamp to suppress the spike through switch which leads increase overall system efficiency. Moreover, peak semiconductors of converter low. existence soft-switching such zero-current switching (ZCS) in OFF-state zero...

This paper presents a ZVS PWM inverter with voltage clamping technique using only a single auxiliary switch. The structure is particularly simple and robust. It is very attractive for single-phase high power applications. Conduction and switching losses are reduced due to implementation of the simple active snubber circuit, that provides ZVS conditions for all switches, including the auxiliary ...
